KLF5 and hepatocellular carcinoma: It also turned out that KLF5 silencing enhanced the inhibitory effect of CD8+ T cells on HCC cell vitality, whereas M2‐exos and galectin‐3 overexpression reversed the above effect, and galectin‐3 overexpression further increased cell vitality in M2‐exos and sh‐KLF5 co‐treated HCC cells (Figure 6G).
